Optimum filter coefficients are calculated by minimizing the deviation of actual frequency response from specified or desired response. Efficiency of the designed filter is measured by several parameters, such as maximum pass-band ripple, maximum stop-band ripple, mean attenuation in stop band and time taken, to execute the code. Analysis of the performance of designed filter is correlated with various different algorithms like real coded genetic algorithm, particle swarm optimization, genetic search algorithm and hybrid particle swarm optimization gravitational algorithm. Comparative study shows significant reduction in pass-band error, stop-band error and execution time. <\/jats:p>","DOI":"10.1142\/s0218126620501558","type":"journal-article","created":{"date-parts":[[2019,10,25]],"date-time":"2019-10-25T06:38:58Z","timestamp":1571985538000},"page":"2050155","source":"Crossref","is-referenced-by-count":16,"title":["Design of Optimal Two-Dimensional FIR Filters with Quadrantally Symmetric Properties Using Vortex Search Algorithm"],"prefix":"10.1142","volume":"29","author":[{"given":"Suman","family":"Yadav","sequence":"first","affiliation":[{"name":"Department of Electronics and Communication Engineering, Bharati Vidyapeeth College of Engineering, New Delhi-110063, India"},{"name":"Department of Electronics and Communication Engineering, Indira Gandhi Delhi Technical University for Women (IGDTUW), New Delhi-110006, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richa","family":"Yadav","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, Indira Gandhi Delhi Technical University for Women (IGDTUW), New Delhi-110006, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ashwni","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, Indira Gandhi Delhi Technical University for Women (IGDTUW), New Delhi-110006, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6578-9741","authenticated-orcid":false,"given":"Manjeet","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, Bennett University, Greater Noida, Uttar Pradesh-201310, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2019,12,16]]},"reference":[{"key":"S0218126620501558BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/ICASSP.2012.6288387"},{"key":"S0218126620501558BIB002","doi-asserted-by":"publisher","DOI":"10.1016\/j.bspc.2017.09.020"},{"key":"S0218126620501558BIB003","doi-asserted-by":"publisher","DOI":"10.1016\/j.cmpb.2013.05.009"},{"key":"S0218126620501558BIB004","doi-asserted-by":"publisher","DOI":"10.1109\/ICAIET.2014.26"},{"key":"S0218126620501558BIB005","first-page":"278","volume-title":"Proc. 7th Int.
